Unfortunately, the game suffers from a substantial obstacle: The control!
One can only control the monkeys almost exclusively on local analog joystick. As if that were not hard enough would be in a 3D world, this control is to also implemented much too sensitive and extremely unintuitive. The smallest movement that deviates from the optimum, resulted - depending on the level - directly in a loss of life.
It is beyond me how this control has made it to publication. Too bad about the money!
